Chan Shen (Chinese: 詹森, 11 March 1940 - 26 April 1984) was a Taiwanese-born Hong Kong film actor. He is best known for his roles as gangsters or villains in Hong Kong action cinema in the 1970s.

Already an established film actor in Taiwan, he entered the Hong Kong film industry in 1971. He was a particularly prolific actor and would often appear in as many as ten films a year. In his fourteen-year film career in Hong Kong, he appeared in 160 action films.

Much of his career was spent at Hong Kong's Shaw Studio. He died because of a brain hemorrhage 26th of April 1984.

詹森曾投考台湾国联公司，受导演宋存寿赏识进入影圈。多扮演坏人，也是李翰祥喜欢的演员。作品超过七十部，是邵氏影迷最熟悉的演员之一。

当年田丰要离开邵氏，何冠昌特意从台湾找来詹森顶替这位“硬里子”演员。詹森外型与田丰相似，初来邵氏只做替身特约，拍《十四女英豪》时田装病，就是詹森做替身。田丰虽为詹森配音，但却认定谷峰才是自己的接班人。

詹森在邵氏演戏虽多，但表现平平，扬名反而是大拍风月床戏。

1976年，詹森与著名艳星余莎莉结婚，但不久便以离异告终。
